Major biosensors in 2014


time:2018-11-05 10:10:24

Technological development in sensor field directly affects product iteration, cost control and user experience of mobile medicine, which deserves close attention of Internet medical entrepreneurs and investors. Especially in the field of wearable devices, it has a direct impact on data acquisition capability.

According to a new report released recently by PMR (Persistence Market Research), a world-renowned Market Research company, the biosensor market will experience rapid growth in the next six years, with a market value of $12.9 billion in 2014 and $22.5 billion in 2020, with a composite annual growth rate of 9.7% by geography. North America is the world's largest market for biosensors, with a market value of US$5.7 billion in 2014, and is expected to reach US$9.5 billion by 2020, with a compound annual growth rate (CAGR) of 8.9% in the forecast period. The Asia-Pacific region will become a region with expanding health insurance coverage, a large population base and an upgrading health care system. The fastest growing region.

Among them, the research group of Sensing Technology Research Institute of Gansu Academy of Sciences believes that sensors will develop in five directions in the future: functional diversification, miniaturization, intellectualization and integration, three high and one low, and joint development of other technologies.

1) Diversification of functions: future biosensors will further involve medical care, disease diagnosis, food detection, environmental monitoring, fermentation industry and other fields;

2) Miniaturization: With the development of microelectromechanical systems and nanotechnology, biosensors will tend to be miniaturized. The emergence of various portable biosensors makes it possible for people to diagnose diseases at home and detect food directly in the market.

3) Intelligence and integration: In the future, biosensors and computers will be more closely integrated to realize the automation system of detection. With the chip technology entering the field of biosensors more and more, the biochip system with chip structure characteristics will realize the integration and integration of detection process.

4) Low cost, high sensitivity, high stability and long life: With the continuous progress of biosensor technology, it is necessary to continuously reduce product costs, improve sensitivity, stability and prolong life. The improvement of these characteristics will also accelerate the marketization and commercialization of biosensors.

5) Biosensors will continue to be combined with other analytical techniques, such as flow injection technology, chromatography and so on, to complement each other's strengths and weaknesses.

The following are new technologies for biosensors in 2014:

Major events of biosensor technology in 2014

Real time biosensor for sweating in November, (USA)

Electrozyme, a sweat data analysis company founded by Joshua Windmiller and Jared Tangney, has developed a wristband product with built-in biosensors that can contact the skin surface of users and read chemical information from their sweat, and then display it. How does the user's body react after strenuous exercise?

Intraocular lens glaucoma sensor August (USA)

Stanford University's research team developed a glaucoma sensor for intraocular lenses. The sensor connects to an external smartphone and a working program and is attached to the human body to measure fluid pressure in the eyeball. This is a method of measuring blindness caused by glaucoma.

New sensor for saliva blood glucose detection in July (USA)

Scientists at Brown University have developed a new sensor for diabetics that uses saliva instead of blood to detect blood sugar levels. The new sensor consists of light sources, metals and a special enzyme that changes color when exposed to blood sugar.

In June, catfish can be used to detect objects in the dark.

John Caprio and his colleagues have developed sensors that allow catfish to sense their prey's breath and help them hunt in what they call home's dark, muddy water.

Skin biosensor for monitoring health status of servicemen (USA)

The U.S. Army has developed a flat electronic chip skin biosensor embedded in a bandage, designed to track the fluids in soldiers'sweat to monitor their health and improve their performance.

New sensor protein molecules are expected to reduce blood concentration monitoring costs (Switzerland)

Researchers at the Federal Institute of Technology in Lausanne have introduced a new type of light emission sensor protein, which can quickly reveal the drug content in patients'blood by changing the color of light. This method is very simple and can be easily operated by patients themselves.

New electrochemical sensor for detecting lean meat in May (China)

Clenbuterol, commonly known as clenbuterol, is a powerful selective agonist, which can promote the synthesis of proteins in skeletal muscle, enhance the decomposition of fat in vivo and inhibit its synthesis. After animal consumption, it can effectively reduce fat deposition in the body and increase the ratio of lean meat to fat in ketone body. After eating this kind of meat products, clenbuterol can break down fat into free fatty acids into the blood, causing blood pressure to rise. Wang Bidou's research group of Suzhou Institute of Biomedical Engineering Technology, Chinese Academy of Sciences has developed a new electrochemical sensor for the specific detection of clenbuterol.

Novel nanoscale sensors or boosted cancer therapy based on DNA sequences (Italy)

Researchers at the Second University of Rome, Italy, have developed a new tool using DNA to detect and respond to chemical changes in cancer cells, which may help deliver drugs successfully to cancer cells for action.

New sensor molecules will help early detection of cancer in April (Finland)

Professor Kari Rissanen's team has found a new water-soluble fluorescence detection system, which is highly sensitive to pyrophosphate (PPi), and pyrophosphate plays a key role in energy transduction, DNA replication and cancer cell dysfunction. The discovery may lead to the development of early detection methods for cancer cells.

March intelligent micro electrochemical biosensor for one-step immunoassay (China)

A bubble-mediated electrochemical biosensor has been developed by the Physical and Biological Research Laboratory of Shanghai Institute of Applied Physics, Chinese Academy of Sciences. The key technology of one-step immunoassay has been solved, and the rapid and sensitive detection of many important disease markers has been realized, which is expected to provide a portable on-site biochemical detection. New means.

Flexible pressure sensors make artificial skin possible (China)

WenlongCheng and colleagues have developed a sandwiched between two electrodes embedded in a thin polymer flexible pressure sensor tissue composed of gold nanowires. The performance of the sensor and the sensor has the same sensitivity, but also used a microphone and application for monitoring heart rate. These sensors make us from achieving flexible touch screen display, man-machine interface device and artificial skin, future electronic devices one step closer.

Progress in research on wearable Flexible Biomimetic nanometers (China)

China Suzhou Institute of nanotechnology and nano bionics research institute researcher Zhang Ting led the team developed a new type of flexible wearable bionic bionic artificial electronic skin tactile sensor, realizes accurate detection of speech recognition and different body physiological state.

Disposable diaper sensor February (Japan)

University of Tokyo professor Someya Takashio and others developed a disposable sensor. The sensor can be embedded in baby diapers. When diapers are wet and need to be replaced, the sensor will use wireless signals to inform adults who care for babies to change diapers. The sensor can also be pasted directly on the skin like a plaster to replace the ring-like instruments commonly used in hospitals, which are often used to measure patients'pulse and blood oxygen content. This sensor can monitor humidity, pressure, temperature and other phenomena that will change resistance.

In January, flexible transducers were transferred to the surface of biological tissues (Switzerland).

Giovanni Salvatore and his team have developed a way to transfer thin, flexible, transparent electronic devices to almost any surface. Devices can even be wrapped around a human hair and continue to function. In addition to biocompatibility, this result provides new possibilities for intelligent contact lenses that may be used for health monitoring.
